ABSTRACT:
An MOS semiconductor circuit includes cascade connected logical circuits. The MOS semiconductor circuit further includes an MOS transistor circuit having at least one first MOS transistor coupled between a source voltage terminal and the output node of the individual logical circuits, and a second MOS transistor, which has the same conductivity type as the first MOS transistor and has its gate and drain short-circuited, with this gate being coupled to the gate of the first MOS transistor. The MOS semiconductor circuit also includes a current control circuit, which is coupled to the drain of the second MOS transistor for providing a predetermined current between the source and drain of the second MOS transistor.
